The order includes more than 1,000 species in about 153 genera. Much like a spider, the body of a Solifugid is separated into an opisthosoma (abdomen) and a prosoma (a combined head and thorax). Unlike scorpions, they do not have tails, and they do not have venom.
Most species of Solifugids live in dry climates. They are found in Europe, Asia, Africa and the Americas. The largest species grow to a length of 12–15 cm (5–6 in), including legs. They are not normally dangerous to people.
